Description

Eremaea atala is a small, erect shrub with spreading branches, growing to a height of 1.2 metres (4 ft). The leaves are 7.3–10 millimetres (0.3–0.4 in) long, 0.8–1.5 millimetres (0.03–0.06 in) wide, flat, narrow egg-shaped with the narrower end towards the base and have a single vein visible on the lower surface. Unlike some others in the genus Eremaea, the leaves are soft and lack a prickly end.[2][3]

The flowers are purple-coloured and arranged in groups of mostly three in the angles of the leaves, mostly along the current year's growth. There are 5 sepals which are densely hairy on the outside surface and 5 petals 3.2–4.5 millimetres (0.1–0.2 in) long. The stamens, which give the flower its colour, are arranged in 5 bundles, each containing 19 to 20 stamens. Flowering occurs from November to January and is followed by fruits which are woody capsules. The capsules are more or less cup-shaped, smooth and 5.0–5.5 millimetres (0.20–0.22 in) long.[2]

Taxonomy and naming

Eremaea atala was first formally described in 1993 by Roger Hnatiuk in Nuytsia.[2][4] The specific epithet (atala) is from the Ancient Greek atalos meaning "soft" or "delicate"[5][6] referring to the soft leaves of this species compared to those of the closely related Eremaea violacea and Eremaea hadra.[2]

Distribution and habitat

Eremaea atala is found between the Arrowsmith and Hill Rivers[2] in the Geraldton Sandplains and Swan Coastal Plain biogeographic regions.[3] It grows in sand over laterite.[7]

Conservation

Eremaea atala is classified as "not threatened" by the Western Australian Government Department of Parks and Wildlife.[3]
